    Set bytecode budget to interrupt_budget when allocating feedback vector · 443721bd
    Mythri A authored
    We use the same interrupt to both allocate feedback vectors and
    for updating the profiler ticks. If there is a feedback vector already
    available, we just increment the profiler ticks that we use to mark
    for optimizing function. Calling JSFunction::EnsureFeedbackVector
    allocates a feedback vector, but doesn't reset the budget, so we
    optimize much earlier than expected. This is currently only a problem
    with %PrepareFunctionForOptimize that doesn't reset the budget. Other
    code paths do also reset the interrupt budget.
